I noticed that /bin/bash.exe has several library dependencies:
~> cygcheck /bin/bash.exe
D:\bin\cygwin1.dll
D:\bin\cygintl-8.dll
D:\bin\cygiconv-2.dll
D:\bin\cygreadline6.dll
D:\bin\cygncurses-8.dll
(as well as other requirements under c:\Windows\system32\ not listed
here). I was able to build a "static" version (that is, a version
requiring only a co-located cygwin1.dll to run) by defining
~> export CFLAGS="-static"
and then building bash from source*.
I was able to do the same thing with nano.exe, which in its "non-static"
standard form requires all of cygncurses-8.dll, cygintl-8.dll,
cygiconv-2.dll as well as cygwin1.dll.
I then tried (because it provides a nicer look than bash)
~> cygcheck /bin/rxvt.exe
D:\bin\cygwin1.dll
and guessed that /bin/rxvt.exe already was "static" in the sense that it
would require only a co-located cygwin1.dll to run; but when I tried it
in that sparse environment I got the error message:
failed to load libW11.dll
Q1. Can anybody tell me why cygcheck /bin/rxvt.exe does not show
libW11.dll as a dependency?
I then tried building rxvt from source* with the same setting for
CFLAGS, but although an executable built perfectly well, it was not
static either. And in the same way: it needs libW11.dll.
Q2. Please can anybody tell me how to build static executables (in
general) in Cygwin, from source*?
* What I mean by "source" is the .tar.gz from GNU or SourceForge or ...
Thank you.
Fergus
